ARTHUR STEIN, OF LONDON, ENGLAND.

MIXING-MACHINE Specification of Letters Patent.

To all whom it may concern:

Be it known that I, ARTIiUR STEIN, chemical engineer, a subject of the Emperor of Austria-Hungary, residing at 36 Mark Lane,

in the city of London, England, have in- 1904, No. 23,334, and still pending, the Patent Oflice having taken no action thereon) of which the following is a specification.

- This invention relates to a machine for making mixtures of saccharine liquids and absorbents such as moss-peat and the like. By moss-peat is meant the product resulting from natural or artificial drying or humiflcation of Sphagnum moss and other peatplants. -Moss-peat and similar substances mixed with molasses and other saccharine liquids are particularly adapted for feeding animals, horses, cattle, sheep and others. In mixtures the moss-peat, &c., acts as an absorbent and vehicle for the saccharine liquid. The production of such mixtures has hitherto been a purely empirical process, no means having been known to vary the pro portion of the constituents in accordance with their varying qualities (humidity, purity, richness &c.), so that even in a given batch considerable diflerences in quality are apt to be found. By this invention such defects are remedied and perfectly uniform mixtures are obtainable.

My improved apparatus is shown in the accompanying drawings in which:

Figure 1 is a longitudinal section of the Whole. Fig. 2 a transverse section of the mlxer.

I-provide a suitabTe vessel in which the saccharine liquid, say molasses is heated, such heater may be of any suitable construction and forming no part of my inventionis not shown in the drawings. a suitable degree the molasses orthe like flow in to the regulator-vessel B. This vessel has a float S acting upon a valve k in the inlet pipe in such a manner as to maintain a constant level in B. The outlet pipe 0 is fitted With a'valve the key of which carries a handle a which serves to open and close it and at the same time operates-as an index movmg over scale A and this arrangement per- When heated to mits the quantity of molasses delivered to be accurately graded.-

From the regulator vessel B the predetermined quantity of molasses continuall flows into the mixer (J. This is a trough li (e vessel with or without a steam-jacket and in it rotates a feed screw C The feedscrew or conveyer may be of any suitable character having a continuous blade, or arms, or wings. At a suitable point in the mixer 0 there is an adjustable slide 7' passing over the shaft of the conveyer, r is a pin that enters one of the holes .9 in the slide to hold the same up. By raising or lowering the slide 7' the quantity passing under it can be regulated without alceives uniform rotation from pulley-gear P. When the slide 1 and the valve in the pipe a are set the whole apparatus delivers a uniform product, in which the exact predetermined proportions between molasses, flowing from the vessel B and absorbent fed into hopper V are present and constant. Such uniform mixture is then delivered from the outlet Z to a smaller conveyer Y which feeds the product to a drying apparatus or a drying or by mere turmng over and over continued for a suflicient time,- but the former is preferable.

By the use of the apparatus so constructed I am enabled to make a product that will. be always and in all respects uniform.

The following absorbents may be used; peat-moss, palm kernels, cocoa, rape seed, cotton seed or husk, earth-nut, sesame or sunflower seed, poppy seed, maize, germs and other by-products or raw materials and waste products from manufacture of 0118 and fats; also hay, straw, or ground stems of various plants such as beans, beetroot seedlings, maize cobs, leaves, bran, rlce, oathusks, spent grains, mare, malt germs, hop residue, -yeast residue, products of brewing distilling and wine making, sugar manufacture, bassia flour, bagasse, sawdust, beetroot cuttings, and the like. The resulting molasses-fodder is advantageous in so far as it is a means for feeding animals with molasses in a dry form capable of easy manipulation.
